Triprolidinium dipicrate

In the tripodinium cation of the title compound {systematic name: 2-[(E)-1-(4-methylphenyl)-3-(pyrrolidin-1-ium-1-yl)prop-1-enyl]pyridinium bis(2,4,6-trinitrophenolate)}, C19H24N2+·2C6H2N3O7 , the N atoms on both the pyrrolidine and pyridinium groups are protonated. The pyrrolidine group adopts a slightly distorted envelope configuration. Strong N—H...O cation–anion hydrogen bonds and weak intermolecular N—H...O interactions link the dication and two anions. In both picrate anions, the nitro groups display rotational disorder over two orientations in a 0.605 (6):0.395 (6) ratio. The crystal packing also features weak intermolecular π–π [centroid–centroid distance = 3.8036 (14) ] and C—H...O interactions.
